Haptic Feedback When Screen is Off

[aesdev421]

Hi all,

I am trying to make an app similar to a countdown timer.  When the timer hits 0 it should vibrate the users wrist.  I have just run into a snag where the timer does not keep running and the haptic feedback is not received when the screen is off.

Is there anyway to do this?  Even a round about way works for me.  My only other choice is to keep the screen on while the app is running, but that's clearly a bad solution.

Thanks in advance

You app should keep running with the screen off, unless the user switches to a different app or clockface.

However, clock.ontick() doesn't fire when the display is off. You're probably not using that anyway.

I actually was using clock.tick and didn't realize it was the reason my app wouldn't run in the background.  I guess I should use Javascript setInterval method instead?

Update: Changed from using clock.onTick to setInterval and it works!
